ACYOGIE Pendent Fire Sprinkler Heads 1/2" NPT — 155°F (68°C) Glass-Bulb K80, 6-Pack Copper-Chrome

ACYOGIE 6 Pcs 1/2" NPT pendent fire sprinkler heads are automatic, glass-bulb activated sprinklers rated for 155°F (68°C) that deliver a parabolic spray pattern and K80 flow for dependable indoor protection.

This six-piece set of ACYOGIE pendent sprinkler heads is built for automatic fire-activation in typical indoor spaces. Each head features a 1/2" NPT threaded connection for easy installation on standard piping, a glass bulb that bursts at 155°F (68°C), and a parabolic spray design that directs over 80% of the water toward the protected area. Constructed with a copper-chrome finish and specified for a maximum working pressure of 175 psi (12 bar), these heads are intended for use in residential, commercial, and light industrial applications where pendent coverage is appropriate.

How do these sprinkler heads activate and respond?

Each ACYOGIE pendent head uses a heat-sensitive glass bulb filled with liquid. When ambient temperature at the sprinkler reaches the rated 155°F (68°C), the bulb shatters and releases the plug, allowing water to flow in a designed spray pattern. These are fast-response sprinklers with a nominal K-factor of 80 for effective water distribution.

• Glass-bulb element that breaks at 155°F (68°C) for automatic activation.
• Nominal K80 flow characteristic to deliver appropriate discharge.
• Fast-response design for quicker activation in developing fires.

What spray coverage and pattern can I expect from the pendent type?

The pendent orientation directs water downward in a parabolic spray, concentrating more than 80% of discharge onto the protected floor area below. This spray geometry is especially useful for open interiors where ceiling-mounted coverage is needed. Proper spacing and hydraulic design determine the effective protection area.

• Parabolic spray throws water broadly downward onto the hazard zone.
• Designed to deposit over 80% of the flow onto the floor or target area.
• Best used where ceiling-mounted coverage and downward distribution are required.

Are these sprinklers compatible with standard piping and systems?

Yes — the ACYOGIE heads use a standard 1/2" NPT threaded inlet that fits common sprinkler branch lines and fittings. They are rated for a maximum working pressure of 175 psi (12 bar), making them suitable for many residential and light commercial systems. As with all sprinklers, install according to local code and system hydraulic calculations.

• Standard 1/2" NPT threading for straightforward installation.
• Maximum working pressure up to 175 psi (12 bar) for system compatibility.
• Follow applicable codes and hydraulic design for proper spacing and layout.

What materials and finish are used, and where are these heads typically installed?

These pendent heads are finished in copper-chrome for corrosion resistance and visual consistency with many interior ceilings. Typical installations include homes, offices, retail spaces, warehouses, and light industrial buildings where pendent coverage is appropriate. They are intended for indoor use and as components of a complete sprinkler system.

• Copper-chrome finish for durability and aesthetic blending with interior ceilings.
• Commonly installed in residential, office, retail, mall, warehouse, and factory interiors.
• Designed for indoor, pendent-type applications as part of an automatic system.

Who is this for: Installers, facility managers, contractors, and homeowners looking to outfit indoor spaces with dependable pendent sprinkler coverage will find this six-pack useful. These ACYOGIE heads suit projects that need standard 1/2" NPT compatibility, 155°F activation temperature, and a fast-response K80 discharge pattern within systems designed and approved by qualified professionals.
